BatMan V2 is coming...
As some of you requested, I added a battery hibernation function to empty the batt down to 65% of charge.
In order to keep the device as "green" as possible, the load is either a smartphone or a powerbank and the extra energy is transferred to the connected device
The modification of the first version is quite simple as the 5V was already generated by a bulk down converter. This DC is able to push several amperes and has an ENABLE pin that can be used to suicide at the end of the discharge!

I will publish the circuit once documented...
